I finally got the USB soundblaster up and running, calibrated everything and ran some sweeps. Everything works fine until I enter filters into the FBQ then I get no sound on the next sweep and the only remedy is removing the filters or hitting the bypass button. What am I not doing right?

Be sure all the filters in the channel are set to parametric.

Remove all the filters and then play a tone with REW's Signal Generator (i.e. 50Hz) and have the tone coming through your sub (low volume). Then play with a single filter at 50Hz on the FBQ while the tone is playing to see what happens......

Its an IB set up with 4-18" FiCars and a EP4000 with a FBQ used for movies only. I also have 2-15" sealed boxs in the rear corners for music only. The main speakers have 2 15" woofers per side. The graph is of the IB only I haven't had the time to set up the rears and intagrate the main woofs yet.

The waterfall plot is not looking so good from 15-80hz, even at 500ms never touches the floor. all the room treatments are in except for the carpet and 2 2'x7'x2" 703 traps on the ceiling between the screen and the projector. I have a 2x3' area behind the main speakers that has a 24" floor to ceiling corner traps, I wonder if I bought some more bags if insulation and stacked them in front of the corner traps behind the speakers if that would help? how much does carpet help with ringing bass?
